Ingredients

• 2 tablespoons olive oil, divided
• 1.5 pounds thinly sliced ribeye steak or shaved beef (or ground beef, 80/20 lean)
• 1 large green bell pepper, cored, seeded, and thinly sliced
• 1 medium yellow onion, peeled and thinly sliced
• 2 cloves garlic, minced
• 1 teaspoon salt, divided
• 1/2 teaspoon black pepper, divided
• 1/2 teaspoon dried oregano
• 1/4 teaspoon red pepper flakes (optional, for a little kick)
• 8 ounces cream cheese, softened
• 1/2 cup sour cream
• 1/2 cup mayonnaise
• 1/4 cup milk (any kind)
• 1 teaspoon Worcestershire sauce
• 2 cups shredded provolone cheese, divided
• 1 cup shredded mozzarella cheese
• 1/2 cup shredded sharp cheddar cheese
• Optional: 1/4 cup chopped fresh parsley, for garnish

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
2. Heat 1 tablespoon of olive oil in a large skillet or cast-iron pan over medium-high heat. Add the thinly sliced beef (or ground beef) to the hot pan. Cook, breaking it up with a spoon, until browned and cooked through. If using ground beef, drain any excess fat. Season the beef with 1/2 teaspoon of salt and 1/4 teaspoon of black pepper. Remove the beef from the skillet and set aside.
3. Add the remaining 1 tablespoon of olive oil to the same skillet. Add the sliced green bell pepper and onion. Sauté for 8-10 minutes, stirring occasionally, until the vegetables are softened and slightly caramelized.
4. Add the minced garlic to the skillet with the vegetables and cook for another minute until fragrant. Stir in the remaining 1/2 teaspoon of salt, 1/4 teaspoon of black pepper, dried oregano, and red pepper flakes (if using). Remove the skillet from the heat.
5. In a large mixing bowl, combine the softened cream cheese, sour cream, mayonnaise, milk, and Worcestershire sauce. Whisk until smooth and well combined.
6. Stir in 1 cup of the shredded provolone cheese, all of the mozzarella cheese, and all of the cheddar cheese into the cream cheese mixture.
7. Add the cooked beef and the sautéed bell pepper and onion mixture to the cheese sauce. Gently fold everything together until all ingredients are evenly coated.
8. Pour the entire mixture into the prepared 9×13 inch baking dish and spread it evenly.
9. Sprinkle the remaining 1 cup of shredded provolone cheese over the top of the casserole.
10. Bake for 25-30 minutes, or until the casserole is heated through, the cheese is melted and bubbly, and the edges are lightly golden.
11. For an extra golden, bubbly top, you can carefully broil the casserole for the last 1-2 minutes. Watch it very closely to prevent burning.
12. Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the casserole to set slightly and makes it easier to scoop.
13. Garnish with fresh parsley, if desired, and serve hot.

Cooking Tips and Variations

To truly elevate your Philly Cheesesteak Casserole, consider these expert tips and exciting variations. For the beef, while thinly sliced ribeye or shaved steak is ideal for that authentic texture, good quality ground beef (80/20 lean) works wonderfully and is often more accessible. If using ground beef, ensure you brown it thoroughly and drain any excess fat to prevent a greasy casserole. Don’t overcook the beef in the initial sauté step, as it will continue to cook in the oven. For the cheese, shredding your own provolone, mozzarella, and cheddar from blocks will always yield a creamier, more luxurious melt than pre-shredded bags, which often contain anti-caking agents. If you’re a fan of a sharper cheese profile, consider adding a touch of white American cheese, a traditional choice for cheesesteaks, or even some sharp provolone.

Vegetable variations are where you can really make this casserole your own. While green bell peppers and onions are classic, feel free to add thinly sliced mushrooms for an “extra” cheesesteak experience. Sauté them with the bell peppers and onions until they release their moisture and brown nicely. For those who like a bit of heat, diced jalapeños or banana peppers can be added to the vegetable mix. You could also stir in a tablespoon or two of roasted red peppers for a subtle sweetness and color. If you prefer a richer, more umami flavor, a dash of onion powder or garlic powder can be added to the beef seasoning.

For an even heartier meal, consider adding a base layer. Some enthusiasts swear by lining the bottom of the casserole dish with a single layer of tater tots or even thinly sliced cooked potatoes before adding the beef mixture. This adds another layer of texture and makes the dish even more substantial. If you’re looking for a low-carb alternative, you can easily omit any starchy additions and serve it as is. For meal prepping, you can assemble the casserole completely, cover it tightly with foil, and refrigerate it for up to 24 hours before baking. You might need to add an extra 10-15 minutes to the baking time if cooking from cold. Let it come to room temperature for about 30 minutes before baking for best results.

When serving, this casserole is a complete meal on its own, but it pairs wonderfully with a simple crisp green salad with a vinaigrette dressing to cut through the richness. A side of crusty bread or garlic bread is also fantastic for soaking up any delicious cheesy goodness. Don’t forget a sprinkle of fresh chopped parsley or chives right before serving for a pop of color and fresh flavor. Experiment with different hot sauces on the side for those who like an extra kick. This recipe is incredibly forgiving and adaptable, allowing you to tailor it to your family’s specific tastes and dietary preferences.

Storage and Reheating

Storing and reheating your Philly Cheesesteak Casserole is straightforward, making it an excellent option for meal prep or enjoying leftovers. To store, allow the casserole to cool completely to room temperature. Once cooled, cover the baking dish tightly with plastic wrap or aluminum foil, or transfer individual portions to airtight containers. The casserole will keep well in the refrigerator for 3-4 days. For longer storage, you can freeze the casserole. Once cooled, wrap it very tightly in several layers of plastic wrap and then aluminum foil, or transfer cooled portions to freezer-safe containers. It can be frozen for up to 2-3 months. Thaw frozen casserole overnight in the refrigerator before reheating.

To reheat individual portions from the refrigerator, the microwave is your quickest option. Place a serving on a microwave-safe plate, cover loosely, and heat on high for 2-3 minutes, or until thoroughly heated through. Stir halfway through to ensure even heating. For larger portions or the entire casserole, reheating in the oven is recommended to maintain the best texture, especially the cheesy top. Preheat your oven to 300°F (150°C). Cover the casserole dish loosely with aluminum foil to prevent the cheese from drying out. Bake for 20-30 minutes, or until heated through. If reheating from frozen, it could take 45-60 minutes or longer, ensuring it’s thawed first is best. For a crispy cheese topping, remove the foil for the last 5-10 minutes of reheating.

Frequently Asked Questions

Can I make this casserole ahead of time?

Absolutely! You can assemble the entire casserole, up to the point of baking, cover it tightly with plastic wrap or foil, and refrigerate it for up to 24 hours. When you’re ready to bake, let it sit at room temperature for about 30 minutes before placing it in the oven. You may need to add an extra 10-15 minutes to the baking time.

What kind of beef is best for Philly Cheesesteak Casserole?

For the most authentic flavor and texture, thinly sliced ribeye steak or shaved beef is ideal. However, good quality ground beef (80/20 lean) works wonderfully and is often more readily available and budget-friendly. If using ground beef, ensure you drain any excess fat after browning.

Can I use different vegetables in this casserole?

Yes, you can! While green bell peppers and onions are classic, you can certainly add other vegetables. Sliced mushrooms are a popular addition, often found in “Philly Cheesesteak with everything.” You could also add a small amount of diced jalapeños for a spicy kick, or even some roasted red peppers for a touch of sweetness and color.

How do I prevent the casserole from becoming watery?

To prevent a watery casserole, it’s crucial to properly cook your vegetables. Sauté the bell peppers and onions until they are softened and any excess moisture has evaporated. If using ground beef, make sure to drain any rendered fat before combining it with the other ingredients. The cream cheese, sour cream, and mayonnaise base also help to create a thick, creamy consistency that resists becoming watery.
